Cosse Violette have beautiful deep purple pods which turn dark green on cooking. They have a fine flavour and harvests over a long period in either glasshouse or out in the open. Climbing beans such as this variety should be supported much in the same way runner beans are.
This family of beans is frost tender and cannot be sown until the weather has warmed up.
WHEN TO SOW
April to June
Where to Sow
Early sowings can be made underglass at a temperature of 16°C, sow 3 seeds per 8cm (3in) pot filled with seed sowing compost. Outside sowings can be made from May onwards into the growing site 5cm (2in) deep. Sow 2-3 seeds every 20cm(8in) apart with rows spaced 60cm (24in) apart.
What to do next
Seedlings sown underglass should be gradually hardened off before planting outside in late May to the above spacing, once all risk of frost has past. Provide support by canes or netting for plants to climb. Water regularly during dry weather.
July to September.
Also attractive grown as a climber in the flower garden with its purple flowers followed by eye-catching purple beans.
